CUTTER=BAR.

SPECIFICATION forming part of Letters Patent No. 383,057, dated May 15,1888.

(No model.)

To all whom it may concern:

Be it known that I, WILLIAM FRANCIS KEN- DRICK, a citizen of the UnitedStates, residing at Winfield, in the county of Henry and State of Iowa,have invented new and useful Improvements in Gutter-Bars, of which thefol lowing is a specification.

The invention relates to improvements in cutter-bars; and it consists inthe construction and novel combination of parts, hereinafter described,and pointed out in the appended claims.

In the accompanying drawings, Figure 1 represents a perspective view ofa cutter-bar and attachments embodying the said improvements. Fig. 2represents a plan view of the finger-bar detached. Fig. 3 is atransverse section of the two on the line 00 x of Fig. 1. Fig. 4 is aperspective view of one of the an gular plates detached. Fig. 5 is adetail perspective view of one of the holding plates and a portion ofthe cutter-bar and the cutting apparatus.

Referring to the drawings by letter, A designates a finger-bar havingthe guard-fingers a a secured to it in the usual manner. Certain of theguard-fingers a have their guards a cut short, and recesses a are madein the squared ends of said guards, for a purpose hereinafter explained.

13 B are cam or inclined slots made in the finger bar to receive thepins or rollers on the cutter-bar. The said slots each consist of twoequal rectilinear legs, I) b, standing rearward from their obtusemeeting angle b, which is preferably about from one hundred and twentydegrees to onehundred and thirty-five degrees. Three cam-slots areemployed for the smallersized cutter-bars, but for the larger size maybe four in number.

0 is the cutter-bar provided with the usual knives, c, and having on itsinner end the head 0 for the attachment of the driving-pitmam' D D arepins depending from the under side of the cutter-bar, spaced to registerwith the obtuseanglcd cam-slots and having anti-friction rollers d toenter and move in said slots, which have their ends and meeting anglerounded to allow the rollers to move easily and without jar or unduewear.

The rear edge of the cutter-bar is rounded out and widened, as at d,(see Figs. 1 and 3,) in rear of the pins D, so that the cam-sl0ts willbe at all times covered and no foreign matter be introduced therein toclog the rollers d.

E E are angular retainingbars, having their feet 6 bolted to thefinger-bar in rear of the cutter-bar, and the arms e extending forwardover the latter. There are preferably two of these bars between each twoof the cam slots, as shown in Fig. 2, and one between each end of thefingerbar and the adjacent cam-slot.

F F are rectangular plates, having their front ends, f, pointed to enterthe recesses a in the rear ends of the short guards of the correspondingfingers a, and in the rear ends of the arms f, bent downward and restingupon the finger-bar in rear of the cutter-bar. The said plates are keptin position by the front ends in said recesses a and'by the bolts f,which pass up through the finger-bar and are engaged by nuts above thesaid plates.

. G G are set-screws, which enter tapped rethe top of the knives c atthe rear portion thereof.

These plates F are secured to the finger-bar and guardfingers a in suchpositions as to cross the meeting angles of the camslots, so that theset-screws not only hold the cutter-bar down to the finger-bar and takeup the wear of the two, but more particularly prevent the anti-frictionrollers from rising out of the cam slots.

It is evident that as the cutter-bar reciprocates the anti-frictionrollers, moving in the cam-slots, will give the said bar a front andrear motion and cause the knives to have a very effective shear.

In my experience I have found that thereis no more positive out than thedraw out. I have tested a cainslot in the form of an arc of a circle,but no motion is so easy and so positive as that produced by theobtuse-angle camslot.

Having thus described my invention, I claim-- 1. The combination, withthe cutter-bar, the finger-bar, and the guard-fingers a, having shortguards and recesses a in the rear ends of said guards, of theholding-plates having their points engaging said recesses and havingtheir rear ends bent down and bolted to the finger-bar, and the setscrews engaging tapped recesses in the lower surface of theholdingplates and bearing on the upper surface of the cutter-bar, as setforth.

2. The combination, with the cutter-bar, the pins depending therefromand having antifriction rollers on their ends, and the fingerbar havingthe obtuse-angled cam-slots to receive said pins, of the plates F,secured to the finger-bar and extending over the cutter-bar and acrossthe meeting angle of the cam-slots,

and the set-screws engaging the under side of said plates and bearing onthe upper side of the cutter-bar, substantially as described.

8. The combination of the finger-bar having the obtuse-angled cam-slotsand the cutter-bar having the pins depending therefrom and engaging saidslots, and the widened portions (1 in rear of said pins, as set forth.

In testimony thatl claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM FRANCIS KENDRICK.
